Does increasing membrane permeability affect the time it takes for the osmometer to reach equilibrium?

It should. The permeability of a membrane defines how fast substances move across a membrane from a high concentration environment to the lower concentration environment. The more permeable the membrane the sooner equilibrium is reached when the concentrations on both side are the same.

Does altering the permeability of the membrane change the equilibrium concentration of the solute in the cell?
yes
What are facts about permeability?
Changes in permeability are changes in the number of compounds that can pass through a membrane. The presence of certain chemicals or radiation can change the permeability of a membrane.
What is the ability of a cell membrane to allow material to pass through it called?
permeability
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
What membrane allows materials to pass into and out of the cell?
Permeability
Does altering the permeability of the membrane change the equilibrium concentration of the solute in the cell?
yes
What feature of a membrane describes whether molecules can cross the membrane?
permeabiity
Why does cholesterol lower membrane permeability?
It sticks to the phosphate heads, preventing motion and increasing hydrophobic reactions.

What is osmosis controlled by?
Osmosis is controlled by the permeability of the osmotic membrane and the equilibrium of the solutions on either side of the membrane. If the solutions have unequal concentrations or osmotic pressures, and the molecules in the solution can pass through the membrane, then the solutions will mix until both sides have equal concentrations. If the membrane is impermeable, then nothing will happen.

What Hyperpolarizing membrane potential occurs in the postsynaptic membrane of a synapse?
Hyperpolarization means that the membrane potential becames more negative than the resting potential. This means that it is more difficult for an action potential to be triggered at the postsynaptic membrane. This occurs at inhibitory synapses. Hyperpolarization can be achieved by increasing the permeability of the membrane to potassium or chloride ions. If potassium permeability is increased more potassium ions will leave the cell, down their concentration gradient; if chloride permeability increases chloride ions will enter the cell down their concentration gradient. Both movements will make the inside of the cell more negative ie they will cause hyperpolarization.
What is the permeability of the cell membranes?
A membrane is selectively permeable.
What membrane allows materials to pass into and out of the cell?
Permeability
